Leopard Cat (Prionailurus bengalensis)

Description

The leopard cat (Prionailurus bengalensis) is a small wild cat of South and East Asia. Since 2002 it has been listed as Least Concern by IUCN as it is widely distributed but threatened by habitat loss and hunting in parts of its range. There are twelve leopard cat subspecies, which differ widely in appearance. The leopard cat's name is derived from the leopard-like spots prevalent in all subspecies, but its relation to the leopard is distant. Leopard cats are about the size of a domestic cat, but more slender with longer legs and well-defined webs between the toes. Their small head is marked with two prominent dark stripes, their short and narrow muzzle white. There are two dark stripes running from the eyes to the ears, and smaller white streaks running from the eyes to the nose. The backs of their moderately long and rounded ears are black with a central white spot. Body and limbs are marked with black spots of varying size and colour, and along the back are two to four rows of elongated spots. The tail is about half the size of their head-body-length and spotted with a few indistinct rings near the black tip. The background colour of their spotted fur is tawny with a white chest and belly. But in their huge range, they vary so much in coloration and size of spots as well as in body size and weight that initially they were thought to be several different species. The fur colour is yellowish brown in the southern populations, but pale silver-grey in the northern ones. The black markings may be spotted, rosetted, or even forming dotted streaks, depending on the subspecies. In the tropics, leopard cats weigh 0.55 to 3.8 kg (1.2 to 8.4 lb), have a head-body-length of 38.8 to 66 cm (15.3 to 26 in) with a 17.2 to 31 cm (6.8 to 12 in) long tail. In northern China and Siberia, they weigh up to 7.1 kg (16 lb), and have a head-body-length of up to 75 cm (30 in); generally, they put on weight before winter and become thinner until spring. Shoulder height is about 41 cm (16 in). In 1792, Robert Kerr first described a leopard cat under the binominal Felis bengalensis in his translation of Carl von Linné’s Systema Naturae as being native to southern Bengal. Between 1829 and 1922, different authors of 20 more descriptions classified the cat either as Felis or Leopardus.[ Owing to the individual variation in fur colour, leopard cats from British India were described as Felis nipalensis from Nepal, Leopardus ellioti from the area of Bombay, Felis wagati and Felis tenasserimensis from Tenasserim. In 1939, Reginald Innes Pocock subordinated them to the genus Prionailurus. The collection of the Natural History Museum in London comprised several skulls and large amounts of skins of leopard cats from various regions. Based on this broad variety of skins, he proposed to differentiate between a southern subspecies Prionailurus bengalensis bengalensis from warmer latitudes to the west and east of the Bay of Bengal, and a northern Prionailurus bengalensis horsfieldi from the Himalayas, having a fuller winter coat than the southern. His description of leopard cats from the areas of Gilgit and Karachi under the trinomen Prionailurus bengalensis trevelyani is based on seven skins that had longer, paler and more greyish fur than those from the Himalayas. He assumed that trevelyani inhabits more rocky, less forested habitats than bengalensis and horsfieldi. Between 1837 and 1930, skins and skulls from China were described as Felis chinensis, Leopardus reevesii, Felis scripta, Felis microtis, decolorata, ricketti, ingrami, anastasiae and sinensis, and later grouped under the trinomen Felis bengalensis chinensis.In the beginning of the 20th century, a British explorer collected wild cat skins on the island of Tsushima. Oldfield Thomas classified these as Felis microtis, which had been first described by Henri Milne-Edwards in 1872. Two skins from Siberia motivated Daniel Giraud Elliot to write a detailed description of Felis euptilura in 1871. One was depicted in Gustav Radde’s illustration cum description of a wild cat; the other was part of a collection at the Regent's Park Zoo. The ground colour of both was light brownish-yellow, strongly mixed with grey and covered with reddish-brown spots, head grey with a dark-red stripe across the cheek. In 1922, Tamezo Mori described a similar but lighter grey spotted skin of a wild cat from the vicinity of Mukden in Manchuria that he named Felis manchurica. Later both were grouped under the trinomen Felis bengalensis euptilura. In the 1970s and 1980s, the Russian zoologists Geptner, Gromov and Baranova disagreed with this classification. They emphasized the differences of skins and skulls at their disposal and the ones originating in Southeast Asia, and coined the term Amur forest cat, which they regarded as a distinct species. In 1987, Chinese zoologists pointed out the affinity of leopard cats from northern China, Amur cats and leopard cats from southern latitudes. In view of the morphological similarities they did not support classifying the Amur cat as a species.

The initial binomial euptilura given by Elliott[22] was eventually changed to euptilurus referring to the ICZN Principle of Gender Agreement; at present, both terms are used.
 

Distribution and Habitat

Leopard cats are the most widely distributed Asian small cats. Their range extends from the Amur region in the Russian Far East over the Korean Peninsula, China, Indochina, the Indian Subcontinent, to the West in northern Pakistan, and to the south in the Philippines and the Sunda islands of Indonesia. They are found in agriculturally used areas but prefer forested habitats. They live in tropical evergreen rainforests and plantations at sea level, in subtropical deciduous and coniferous forests in the foothills of the Himalayas at altitudes above 1,000 m (3,300 ft).[3] In 2009, a leopard cat was camera trapped in Nepal’s Makalu-Barun National Park at an altitude of 3,254 m (10,676 ft). At least six individuals inhabit the survey area, which is dominated by associations of rhododendron, oak and maple.[4] In the northeast of their range they live close to rivers, valleys and in ravine forests, but avoid areas with more than 10 cm (3.9 in) of snowfall. They are rare in Pakistan’s arid treeless areas.
In Sabah’s Tabin Wildlife Reserve leopard cats had average home ranges of 3.5 km2 (1.4 sq mi).[7] In Thailand’s Phu Khieu Wildlife Reserve 20 leopard cats were radio-collared between 1999 and 2003. Home ranges of males ranged from 2.2 km2 (0.85 sq mi) to 28.9 km2 (11.2 sq mi), and of the six females from 4.4 km2 (1.7 sq mi) to 37.1 km2 (14.3 sq mi) The leopard cat is a widespread species in Asia. It is found throughout most of India west into Pakistan and Afghanistan (Habibi 2004), through the Himalayan foothills, across most of China, and north to the Korean peninsula and into the Russian Far East (Nowell and Jackson 1996). It is found throughout Southeast Asia, and on the islands of Sumatra, Java, Borneo and Taiwan. It is found on numerous small offshore islands of mainland Asia (Nowell and Jackson 1996, Sunquist and Sunquist 2002). The leopard cat is the only wild felid found in the Japan, where it occurs on the small islands Tsushima and Iriomote, and the Philippines, where it occurs on the islands of Palawan, Panay, Negros and Cebu. In the Philippines, there are recent (2007) unconfirmed reports from the island of Masbate. It should be present in Guimaras due to proximity to Negros and Panay, but no presence was reported, and is therefore presumed to be extinct (R. Lorica and W. Oliver, unpub.).

Prionailurus bengalensis alleni (Sody, 1949) — Hainan Island.
Prionailurus bengalensis iriomotensis (Imaizumi, 1967) — found exclusively on the tiny island of Iriomote, one of the Ryukyu Islands in the Japanese Archipelago.
Prionailurus bengalensis heaneyi (Groves 1997) — the Philippine island of Palawan.
Prionailurus bengalensis rabori (Groves 1997) — the Philippine islands of Negros, Cebu, and Panay.
The Iriomote cat (P.b. iriomotensis) has been proposed as a species since 1967, but following mtDNA analysis in the 1990s is now considered a subspecies of the leopard cat.
The Tsushima leopard cat lives exclusively on Tsushima Island. Initially regarded as belonging to the Chinese leopard cat subspecies, it is now considered an isolated population of the Amur cat P. b. euptilurus/euptilura

Population:

The leopard cat is the most frequently recorded small cat across most of its wide range, in comparison with sympatric species (Nowell and Jackson 1996, Duckworth et al. 1999, Holden 2001, Duckworth et al. 2005, Lynam et al. 2006, Yasuda et al. 2007), and with its broad distribution has an abundant population. However, it is probably declining due to habitat loss and hunting. Large numbers of leopard cat furs were exported from China (averaging 200,000 skins per year in the late 1980s) (Nowell and Jackson 1996). Higher survival rates (92%) were recorded in a protected area with little human influence, compared with lower rates in areas with greater human activity (53-82%) (Haines et al. 2004). While the leopard cat is more tolerant of disturbed areas than other small Asian felids, it likely undergoes higher mortality in such areas. Island populations are most at risk of extinction, with the Iriomote cat P.b. iriomotensis listed as Critically Endangered, and the Visayan leopard cat P.b. rabori of the Philippine islands of Panay, Negros, Cebu and possibly Masbate listed a Vulnerable. The small population (approximately 100) on Japan's 710 km² Tsushima Island, considered the same subspecies as occurs in northeastern mainland Asia, has decreased over the last 30-40 years (Izawa et al. 2007).
Population Trend: Stable

Ecology and behavior

Leopard cats are solitary, except during breeding season. Some are active during the day, but most hunt at night, preferring to stalk murids, tree shrews and hares. They are agile climbers and quite arboreal in their habits. They rest in trees, but also hide in dense thorny undergrowth on the ground. In the oil palm plantations of Sabah, they have been observed up to 4 m (13 ft) above ground hunting rodents and beetles. In this habitat, males had larger home ranges than females, averaging 3.5 km2 (1.4 sq mi) and 2.1 km2 (0.81 sq mi) respectively. Each male's range overlapped one or more female ranges. Leopard cats can swim, but seldom do so. They produce a similar range of vocalisations to the domestic cat. Both sexes scent mark their territory by spraying urine, leaving feces in exposed locations, head rubbing, and scratching.

The species can range up to 3,000 m in parts of its range, which extends into the Himalayas along river valleys. It occurs in a broad spectrum of habitats, from tropical rainforest to temperate broadleaf and, marginally, coniferous forest, as well as shrub forest and successional grasslands. The northern boundaries of its range are limited by snow cover; the leopard cat avoids areas where snow is more than 10 cm deep. It is not found in the cold steppe grasslands, and generally does not occur in arid zones, although there are a few records from relatively dry and treeless areas in Pakistan. Leopard cats occur commonly in dense secondary growth, including logged areas, and have been found in agricultural and forest (rubber tree, oil palm, sugarcane) plantations. The species can live close to rural settlements. Leopard cats are excellent swimmers, and have successfully colonized offshore islands throughout their range (Nowell and Jackson 1996; Sunquist and Sunquist 2002). In the most comprehensive study, based on a large sample size of 20 radio-collared cats in Thailand's Phu Khieu Wildlife Sanctuary, mean home range size (95% MCP) was 12.7 km², larger than in other areas of Thailand (4.5 km²) (Grassman et al. 2005), on Borneo (3.5 km²: Rajaratnam 2000), or on Japan's Iriomote island (Schmidt et al. 2003). There was no significant difference between male and female home range size. Open and closed forest habitats were used in proportion to their occurrence, and activity patterns showed crepuscular and nocturnal peaks. On Borneo, Rajaratnam et al. (2007) found that leopard cats hunted rodents in oil palm plantations, and used forest fragments for resting and breeding. Murids dominate the diet (85-90%: Grassman et al. 2005b, Rajaratnam et al. 2007). Other small mammals, eels and fish have also been reported, as well as occasional scavenging of carrion (Nowell and Jackson 1996).
Systems: Terrestrial
Diet
Leopard cats are carnivorous, feeding on a variety of small prey including mammals, lizards, amphibians, birds and insects. In most parts of their range, small rodents such as rats and mice form the major part of their diet, which is often supplemented with grass, eggs, poultry, and aquatic prey. They are active hunters, dispatching their prey with a rapid pounce and bite. Unlike many other small cats, they do not "play" with their food, maintaining a tight grip with their claws until the animal is dead. This may be related to the relatively high proportion of birds in their diet, which are more likely to escape when released than are rodents.
Reproduction and development
There is no fixed breeding period in the southern part of its range; in the colder northern range they tend to breed around March or April, when the weather is mild enough to support newborn kittens. The estrus period lasts for 5–9 days. If the kittens do not survive, the female may come into heat again and have another litter that year. After a gestation period of 60–70 days, two to four kittens are born in a den, where they remain until they are a month old. The kittens weigh about 75 to 130 grams (2.6 to 4.6 oz) at birth and usually double their weight by age of two weeks; at five weeks, they are four times their birth weight. The eyes open at ten days, and the kittens start to eat solid food at 23 days. At the age of four weeks, the permanent canines appear, and the kittens begin to eat solid food. Leopard cats have lived for up to thirteen years in captivity. Leopard cats usually pair for life and raise their kittens together for about 7 to 10 months. Full maturity is reached at 18 months, but in captivity, the male can become ready to breed at 7 months, and the female at 10 months.

Threats

In China, leopard cats are hunted mainly for their fur. Between 1984 and 1989, about 200,000 skins were exported yearly. A survey carried out in 1989 among major fur traders revealed more than 800,000 skins on stock. Since the European Union imposed an import ban in 1988, Japan has become the main buyer, and imported 50,000 skins in 1989. Although commercial trade is much reduced, the species continues to be hunted throughout most of its range for fur, for food, and as pets. They are also widely viewed as poultry pests and killed in retribution. In Myanmar, 483 body parts of at least 443 individuals were observed in four markets surveyed between 1991 and 2006. Numbers were significantly larger than non-threatened species. Three of the surveyed markets are situated on international borders with China and Thailand, and cater to international buyers, although the leopard cat is completely protected under Myanmar's national legislation. Effective implementation and enforcement of CITES is considered inadequate.

Major Threat(s)

China, the centre of its range, commercial exploitation has been heavy: hundreds of thousands of Leopard Cat skins per year were exported in the 1980s. Although commercial trade is much reduced, the species continues to be hunted throughout most of its range for fur, for food, and as pets. They are also widely viewed as poultry pests and killed in retribution. Island populations are small and seriously threatened in the Philippines and Japan. Leopard cats can hybridize with domestic cats, as is shown by the popular domestic breed, the "safari cat". Hybridization in the wild has been reported, but is not considered a significant threat. Although the species is less dependent on forest cover than others, habitat loss and fragmentation is still a major threat across most of its Asian range (Nowell and Jackson 1996).

Conservation Actions:

Included on CITES Appendix II; populations in Bangladesh, India and Thailand are included on Appendix I (as Prionailurus bengalensis bengalensis). The species is protected at the national level over part of its range, with hunting prohibited in Bangladesh, Cambodia, Hong Kong, India, Indonesia, Japan, Malaysia, Myanmar, Nepal, Pakistan, Philippines, Russia, Thailand and Taiwan, and hunting and trade regulations in place in South Korea, Lao PDR and Singapore (Nowell and Jackson 1996, A. Wilting pers. comm. 2008). The species is on Afghanistan’s 2009 Protected Species List, banning all hunting and trading of this species within the country. It is found in numerous protected areas.
